tekstar··on $100M xPrize for Carbon Removal
Also, planting trees sequesters co2 into the biosphere. That is not good enough, we need to be sequestering co2 into the geosphere if we want to remove it from the equation
tekstar··on Death Valley hits 130 degrees, near world record
I visited Death Valley in the summer year ago. I remember the birds would line up in the narrow shadows cast by the telephone poles to stay out of the sun.
tekstar··on Canada battles more than 180 wildfires with hundreds dead in heat wave
Too many big carbon emitters don't shut-down easily, and the cost to start them backup is likely higher (steel processing, container ships, power plants, etc)
tekstar··on Ask HN: Language-agnostic concepts a Backend Engineer should know?
Yeah it's the complete opposite of niche. It's the fundamental understanding of processes, signals, syscalls, memory that every modern computing system is based upon.
tekstar··on Ask HN: Language-agnostic concepts a Backend Engineer should know?
C and how to debug it.

If you understand the system a layer of abstraction or two below the layer you work in, you will be able to debug deeper. Learn system calls, Various ways how to examine processes.

I learnt a lot of this back in the day by completing war games on a site called digital evolution (dievo). Those are antiquated now but still a really fun way to learn it.

tekstar··on Tiny Acquisitions
In this specific case I would sell at a lower multiple to someone in the niche community. The amount of money to be made by selling someone who wants to exploit the userbase isn't worth tarnishing my reputation and subsequently shooting future projects within the same niche in the foot.
tekstar··on Tiny Acquisitions
I have a niche iOS app that makes between $200-400 monthly. I would sell it to someone who would continue to grow it because I would rather build new things than continue to add content to the app.
tekstar··on Brain imaging before and after Covid-19 in UK Biobank
I'm pretty sure we had covid in March 2020, and my wife has since then been extremely tired - like needs a 2 hour nap every afternoon and in bed by 8pm - and brain foggy. She's had concussions in the past, so I haven't been sure when one brain fog ended and the other fog started, but I do wonder if it's post-covid related. I just don't know what to do about it though. Doctors are finding nothing.
tekstar··on Why gold and Bitcoin are popular
I also don't drive a really big car, and I think it's stupid as well.

So, now we're at two things I don't do because they're bad for the environment.

tekstar··on Why gold and Bitcoin are popular
> I think it’s hard to make the argument against allocating somewhere on the order of 1% of your portfolio to crypto.

crypto, especially bitcoin, is an intentional environmental disaster. I don't want to invest 1% of my money into an intentional environmental disaster.

tekstar··on Silicon Valley’s ‘Mission Protocol’ Revolution Beginning to Attain Critical Mass
At least some of these CEOs fomented the wokeness and tried to utilize it until it became a liability.

I worked at one of the companies mentioned in the article, and remember the CEO saying at town halls "there is no better company than <this company> to enact positive change in the world today" and pat themselves on the bat.

tekstar··on The Plan for React 18
Your first sentence is correct. I'm quite happy using it the way I use it and don't hit any really sharp edges.

Thanks for the link, I remember when Hooks came out but I didn't feel the need to adopt them, I'll take a look again.

tekstar··on The Plan for React 18
I use React (well, Preact) every day.

I use it 2014-style. Class-based components, componentWillMount, render, callbacks, and that's about it.

I love this workflow, and generally structure all my UIs this way regardless of platform - have a state struct and then fully render the UI as a function of the state. To me, that's the big hurrah for using React.

But I have no clue why React is at version 18 and why it keeps getting new features. I'm perfectly happy making quite complicated UIs with the pattern I know well. Should I be following along? Does it matter?

tekstar··on Apple brings Safari web browser extensions to iPhone and iPad with iOS 15
Would love to see WebMIDI, but I suspect the options are alternate browsers in the App Store that are WKWebView's implementing it as a shim, or it will have to be added by Apple. I don't think they're letting extensions actually see the DOM.
tekstar··on G7 nations committing billions more to fossil fuel than green energy
I've been thinking about this, and if that CO2 tax results in that less CO2, who feels the brunt of it? What does it look like to people? Is everything 20-50% more expensive, so we buy less of it? Would be great to see the CO2 reduction, but I don't see our government going the route of forced austerity. I guess the idea is to then force low-carbon innovation to bring prices back down?
tekstar··on G7 nations committing billions more to fossil fuel than green energy
I asked the question because I was actually wondering your thoughts, like, maybe I'm being too negative to think what has been done so far has been far from what's necessary. I wasn't trying to be cynical about it.

In terms of suggestions, the book Drawdown contains many. It lists 100 contributing solutions to climate change. I'm going to go read it again, but the gist is that there are no silver bullets.

Two things that were campaign and earlier year promises we've yet to see.. planting 3 billion trees, and ending fossil fuel subsidies.. those still haven't happened.

tekstar··on G7 nations committing billions more to fossil fuel than green energy
Do you think those policies are anywhere on the scale necessary to meet the climate change goals he has set out?
tekstar··on G7 nations committing billions more to fossil fuel than green energy
Our PM also walks behind the US and reiterates whatever climate target they state, like X % by 2030 and y % by 2050. I have seen exactly 0 plan on how to get there. I suspect he'll retire in 2029.
tekstar··on In search of the new
That is awesome!
tekstar··on In search of the new
Big fan of Robin, his books, his blog, his Instagram stories while walking around SF.. all great!
tekstar··on Second-guessing the modern web (2020)
sent you an email, I'd be interested in reading that paper once it's available! Cheers
tekstar··on Second-guessing the modern web (2020)
Nice blog post! I read the whole thing. I'm working on something with multiplayer using an unbounded queue of command events, so I learnt a few things about that situation. If you have any posts that elaborate on the typical infrastructure events from running that in production, I'd love to read it as you obviously put a lot of effort into your blog posts.
tekstar··on Second-guessing the modern web (2020)
Looks like you're trying to reinvent some wheels there.

No harm in doing so but just so you know, React (or my preference, a tinier version called Preact) would let you update new chat contents without blowing away all the other InnerHTML content. The way you're doing it now will result in a flicker, and mess with things like highlighted text will unhighlighted when replaced. And that's just with the basic dumping of the chat text into a DOM innerHTML. I'm pretty sure what you're doing there would also be susceptible to XSS without additional filtering.

tekstar··on Claude Shannon: Tinkerer, Prankster, and Father of Information Theory (2016)
A really good book is "The Idea Factory" by Jon Gertner. It describes Bell Labs in this period, and through the book basically tells the story of where modern life was born: everything from growing crystals to transistors to cell phones to radar was created at Bell Labs.
tekstar··on Canada declares plastics toxic, paving the way for restrictions
Is plastic still that much less energy usage compared to paper when you include the energy needed to recycle it?
tekstar··on Show HN: Tool that turns your images into plotter-like line drawings
I snagged an HP7475a off a local buy and sell site recently for $60. Came with a serial-to-plotter cable (which I only realized after splicing that cable, working out the wiring, and finding it was already the cable I needed :( )

Then I bought a cheap 3d printer and made a few of these, which fit the "fat" sharpies: https://www.thingiverse.com/thing:1261805

I need to adjust that print for "ultra fine" sharpies in order to do prints like what this website is producing though.

tekstar··on Slack was experiencing an outage
Long time ago, the day I finished my probation period at work was also a multi-hour gmail outage. I got up, couldn't load my email, and had a panic attack for a few minutes before finding out what was going on
tekstar··on Pen plotters: not just output devices (2016)
I was going to get an axidraw but on a whim I checked locally and scored a HP7475a for $60 and got it working.

So definitely worth looking around a bit before going with new!

tekstar··on Trans-Pacific deteriorating, brace for shipping ‘tsunami’
Genius comment right here, thanks

This exists at least in one place, with trains on a hill in Nevada.
